[QUOTE="daddys1, post: 762898, member: 134619"] Hi Bluetit, your right as always (well mostly) :facepalm:, Yeah I realized after I had posted that it was [USER=107467]@cold ethyl[/USER] who mentioned the extra blood on the strip. Thought I would just wait to get caught out o_O. Yes I have studied the strips and I do wonder that the mere fact of sometimes touching the top of the strip where the reading contacts are with unwashed hands could effect the readings we have. Even tipping the tub and grabbing 1 is not easy without touching many tops where these contacts are. Anything on those contacts will transfer also to the internal contacts within the testing slot. To be honest though, I have found this little machine quite consistent, when you consider the allowable variance is [B]+ or - [/B]15%, that is a 30% overall. That does mean they would be in tolerance showing levels of say your actual 5mmol/L + 15% an increased reading to 5.75mmol/L, or your 7.5mmol/L +15% would read 8.6mmol/L. These would be numbers we would not be happy with. Conversely could have 15% lower readings and if we were in the predominantly high numbers it would give a false feeling of assurance. If all the strips were showing these high readings that would still be within tolerance, so unless you have a very accurate test to compare it to, it is not easy to gauge anything. I'm using batch 44, I haven't noticed any massive deflection on the readings yet. They'll probably start now.............:( Neil [/QUOTE]
